Huawei HCIP-Transmission V2.0 - H31-341 Exam Questions [2026]

QUESTION NO: 1
The following description of the operation of the device, the error is:

A. Wear an ESD-preventive wrist strap or gloves to prevent static electricity from damaging the board. B. CLASS 1M means low optical power, no damage to eyes or skin C. Regularly clean the air filter to facilitate heat dissipation D. Equipment needs safety grounding

Correct Answer: B

QUESTION NO: 2
Which of the following description of the process for optimizing the line attenuation compensation anomaly is correct? (Multiple choice)

A. The SCC board at the downstream site of the fault reports the alarm to the power detection unit (OA) of the first node through DCN communication, and reports the alarm to the SOM on the SC of the first node. B. After receiving the alarm, the SOM obtains the OCh path corresponding to the alarm and adds it to the management path to be optimized. C. According to the user adjustment command, adjust the line attenuation of the OCh path to make the downstream light output reach the normal value. D. The downstream power detection unit (OA) detects that the line attenuation deviation exceeds the threshold and reports the alarm to its own SCC board.

Correct Answer: B,C,D

QUESTION NO: 7
Which of the following are limitations of the alarm and performance analysis methods? (Multiple Choice)

A. Field maintenance personnel cannot understand the current operating condition of the equipment. B. In the case of complex networking, service, and fault information, many alarms and performance events may occur along with the occurrence of faults. Due to too many reports and performance events, maintenance personnel are unable to analyze. C. The network administrator cannot obtain the current notifications of the device, the alarm occurrence time, and the historical alarm of the device. D. When some faults occur, there may be no obvious alarms or performance events reported, and sometimes no alarms or performance events are found.

Correct Answer: B,D

QUESTION NO: 8
A, C are the WDM OTM stations, and B is the relay station.
When the transmission direction of the A to B stations is interrupted, the Wavelength side of the B-stack OTU relay board reports the R_LOS emergency alarm and runs the processing to the upstream A.
The station side OTU2_BDI secondary alarm. At the same time, the alarm continues to be transmitted to the downstream station of the B station. After the alarm is processed at the C site, the ODU2_PM_AIS minor alarm is reported on the WDM side of the C-site OTU, and the ODU2_PM_BDI secondary alarm is transmitted back to the upstream station A.

A. FALSE B. TRUE

Correct Answer: B
